Application September 25, 1939,'Serial No. 296,354 sciaims. (01. 229-1)Thisinvention relates to the art of packagin commodities. and moreparticularly to dispensing packages. I x

An Object of this invention'is to provide a package embodying a flexibleinner container of sheet material and a structurally strong outer orcarrier receptacle protecting the relatively fragile inner container andcharacterized by extremely simple means manually operable to expose adispensing portion of the inner container which is adapted to projectthrough an opening in the outer receptaclenormally closed by said means,so that the dispensing portion can function as a highly eflicientpouring spout.

Another object of the invention is toprovide a dispensing packagewherein the closure bf the outer receptacle, while adequately protectedagainst accidental disturbing, is readily openable by a simplemanipulation to leave a generally triangular opening in the receptacle,through which is exposed a generally triangular flap of the innercontainer normally folded flat between the container and receptacle atthe closure of the latter, for manipulation of the flat through theopening to a pouring position wherein the flap can also co-act with theedges of the opening in being supported thereby in spout formation'forpouring the contents of the inner container therefrom.

With these and other objects in view, the invention resides in thecombinations and arrangements of elements as set forth in the followingspecification and particularly pointed out in the appended claims.

terial which is impervious, such rubber or Pliofilm, both of which arecapable of being hermetically sealed by the application of heat andpressure to preserve The inner container is folded from a fiat blankinto a rectangular envelope which is filled through one open endsubsequently closed by being folded upon itself to include hollowtriangular flaps l0 suitably sealed along their edges.

The outer receptacle R is constructed of chip board or other cheap sheetmaterial having the requisite structural strength to adequately protectthe inner container C. against injury. The receptacle is formed from theblank shown in Figure 6, the blank being scored to provide fourrectangular panels ll having [2' and I3 at their ends, and one having aside flap M to which a suitable adhesive is applied to secure the sideflap to the inner side of that one having the free side edge so as toenable the blank to be opened to receptacle formation. v

At one end, one of the panels II is perforated alongtwo short lines l5adjacent and parallel to the side edges of the panel, and theseperforations are continued in two converging-straight lines ii to anapex IL. This panel is further perforated from the lines l5 along thejuncture of said one end flap H as indicated tive view of the innertheir contents.

rectangular flaps flaps are folded and secured together bya suitableadhesive (as shown in Figure 1), a fingerengageable portion or piece207wil1 be formed along the length of the slit I9.

The amount" of lateral offset of the slit l9 from the juncture of thepanel H into the flap I2 is such that the height of the resulting piece20 will, in the closed position of the end flaps, not exceed thethickness of the sheet stock from which the receptacle is made. Thus thepiece 20 will not interfere with the stacking of a number of thereceptacles and will not be inadvertently disl6 and I8, and the slit l9co-act to define a generally triangular closure 22 having the piece 20,and which closure is at that end of the receptacle R. through whichthe'filled container C is inserted into the receptacle.

It will be noted that the container C is inserted into the receptacle R.with the flaps III of the container folded fiat between the containerand receptacle, and with one of these flaps directly opposite theclosure 22 as shown in Figure 2.

Furthermore the flaps l correspond in their gen eral outlineto that ofthe closure 22 and are slightly less in size than the latter. Thus, upontearing off the closure along the lines l5, l6 and I8 by pulling uponthe piece 20, said one of the flaps III will be exposed in the resultingopening 23 in the panel H and can readily be swung outwardly through theopening to the pouring position shown in broken lines in Figure 3 tofunction as a pouring spout P, (Figure 4).

By now severing the sealed tip end of the flap H) from the remainder ofthe flap along the line 24, fluid contents of the container can beconveniently poured therefrom in easily controlled quantities.

The converging side edges of the opening 23 are adapted to co-act withthe pouring spout and with the body of the container in limiting theextent to which the spout can be expanded by the weight of the contentsof the container during the pouring operation, and thus efiectivelyconfine the spout against rupture as well as support the spout inpouring position.

I It will thus be manifest that by the above described correlation ofthe closure 22 and the flap It, the opening 23 resulting from theremoval of the closure, co-acts with the flap III in insuring that thelatter will be maintained in the shape of a highly efiicient pouringspout irrespective of the weight of the contents of the containertending to deform the spout. p

Reference will now be had to Figures '7 to 10, inclusive, whichillustrate a modified form of closure 220; for the outer'receptacle R.

In this form of the invention the outer'receptacle R is also constructedof chipboard or other cheap strong material from the blank shown inFigure 10, which is scored to provide the four tions continue in twoconverging straight lines.

The container C is inserted into the receptacle R with the fiaps l0a ofthe container folded fiat between the container and receptacle, and withone of the flaps directly opposite the closure 22a as shown in Figure 9.

. manner previously described.

In the use of the package for heavy liquids such as lubricating oils,the end walls of the inner container C are preferably secured to theflaps l2 of the outer receptacle R by means of a suitable adhesive. Asshown in Figures 11 and 12, this adhesive can be applied along thoseedges of the inner container from which the flaps Ill project, in theform of strips 26 extending .to the corners 21 of the container, or canbe applied tothe end walls or to the flaps I2 to cover the entire areathereof.

The adhesive efiectively anchors the inner container in the outerreceptacle against movement relatively thereto at the corners 21 so thatsurging of'the heavy liquid contents of the inner container resultingfrom handling of the package cannot work the corners 21 back and forthto weaken same and cause leakage of the contents. It will be appreciatedthat surging of. the liquid content will alternately produce suction andpressure at the corners 21, which would ultimately fracture the innercontainer at the junction of the fold lines, were the inner containerentirely loosev in the outer receptacle.

It will be manifest that this feature of the invention greatly enlargesthe range of liquid products which can be marketed in the package, andenables heavy lubricating oils for automotive use to be supplied to theconsumer in quart and other small sizes in a very inexpensive andstructurally strong package capable of being opened to convenientlydispense the contents with the utmost ease and dispatch.
